A sphere of radius 1 \(cm\) is made from silver. If the mass of the sphere is 33 \(g\), find the density of silver. (Take \(π\ =\ 3.14\)).

[NOTE: Enter the answer up to three decimal places].

\(r =\) \(cm\)

\(M =\) \(g\)

The volume of sphere is given as

\begin{array}{l} Volumes of silver sphere = \frac{i}{i} π i^{i} \\ = \frac{i}{i} \times i {\times (i)}^{i} \\ = i g \end{array}

The density of sphere is given as

\(\text{Density} = \frac {\text{Volume}} {\text{Mass}}\)
\(\text{Density} = \frac {\text{Mass}} {\text{Area}}\)
\(\text{Density} = \frac {\text{Mass}} {\text{Volume}}\)

On substituting the known values in the above formula, we get the density of silver sphere is \(g/cm^3\).
